Northern hemisphere summer - is this the big one? (Weather)

Methane, which comes from cows, is worse than CO2 as an planet warmer, but breaks down naturally in the atmosphere at a faster rate than CO2.

The bad news is that the amount of methane is climbing suggesting the break-down reaction is getting slower - possibly due to a 'tipping point' reached whereby the heat level is negatively impacting the chemical reaction in the atmosphere that causes the break-down.
